The Muscle 110 Extreme kit is a no-nonsense hot rod package that delivers thrilling power across the RPM range. It is a combination of the right mix of components and modifications that extracts stunning horsepower and torque from the CVO 110 platform. Zippers’ goal was to break the 150 horsepower barrier on pump gas without creating a narrow power curve that detracts from the riding experience. The Muscle 110 Extreme delivers, with torque breaking 100 ft/lbs from 2,750 rpm through red line, peaking at 130 ft/lbs. Zippers’ Muscle 110″ Extreme.

CVOs best maintain their long term values in stock form. Modify if you like, but be able to change them back. Some 10 year old CVOs are actually going up in value now.

Zipper’s makes stellar products, but this package is $5,800 plus labor. I would think it would make more sense to just buy a hot rod crate engine with a warranty and save the OE numbered 110″ engine for when you want to return it to stock.

Outstanding !!!
If it’s a hot rod (non-Turbo/Supercharger) bike you want, then this is your ticket !
but then I have to ask why would a CVO owner who just spent $40 – 50 K on a bike,
want to spend $6000 more to hot rod it ????
As Marcus said some CVO’s are worth the $$ if you keep them stock !!!
And what’s going to happen when the CVO’s go to the 120ST motor ?
I guess they’ll have a kit for that too ????
